For me, the passion of being an astronaut was ignited at an early age. I have this recollection of looking at a picture of the Apollo program - Neil Armstrong standing on the Moon - then looking at the night sky and realizing that, right where I was looking, people stood and looked back at the Earth. Even as a fairly young child, that was not lost on me, and it inspired me to pursue my dream. I didn't know if I would ever become an astronaut, of course, and the odds are not in your favour, but I just kept it in the back of my mind and tried to keep those options open.
